3020           specified. This was wrong because wxWidgets programs often assume
3021           that they get a WM_SIZE (EVT_SIZE) upon creation, however this broke
3022           it. To see why, you should understand that Windows sends WM_SIZE from
3023           inside ::CreateWindow() anyhow. However, ::CreateWindow() is called
3024           from some base class ctor and so this WM_SIZE is not processed in the
3025           real class' OnSize() (because it's not fully constructed yet and the
3026           event goes to some base class OnSize() instead). So the WM_SIZE we
3027           rely on is the one sent when the parent frame resizes its children
3028           but here is the problem: if the child already has just the right
3029           size, nothing will happen as both wxWidgets and Windows check for
3030           this and ignore any attempts to change the window size to the size it
3031           already has - so no WM_SIZE would be sent.
